You can thank a German physicist named Daniel Fahrenheit. In 1724, he defined his scale using a brine mixture (salt and ice) as zero, the freezing point of water as 32, and human body temperature as 96 degrees.
Modern science adjusted body temp to 98.6°F, but the 32°F freezing point stuck. It’s a wonderfully odd number—neither round nor intuitive—yet it’s become a global shorthand for “brrr.”
Cultural check: When the TV weather anchor says “It’s freezing out there,” they don’t mean windy—they mean exactly 32°F or below. That degree is a cultural signal: time to layer up, scrape windshields, and crank the heat.
